Product Data
Clone Name ER-TR7
Applications FC, IHC
Recommended Dilution Immunohistochemistry on Frozen Sections: 1 µg/ml (1/400) freshly prepared for Mouse tissue and 4 µg/ml (1/100) on Human/Porcine tissue.
Recommended Positive Control: Mouse spleen.
Does not react on routinely processed Paraffin Sections.
Has been described to work in FACS.
Reactivities Human, Mouse, Porcine
Host Rat
Isotype IgG2a
Clonality Monoclonal
Immunogen Murine thymic reticulum.
Epitope: The antigen has not been fully characterized.
The epitope may be part of reticulin.
Specificity Reacts with Mouse reticular fibroblasts, reticular fibres and Human tonsil.
ER-TR7 detects an antigen present in and produced by reticular fibroblasts. The recognized antigen is most likely distinct from Laminin, Fibronectin, Collagen types I-IV, Heparan Sulfate Proteoglycan, Entactin, and Nidogen.
The antibody is useful to stain the microanatomy of various organs, in particular the connective tissue framework in lymphoid organs. The antibody also stains subendothelial deposits in the plaque area of atherosclerotic plaques.
Antigen Distribution
Isolated Cells: The antigen is found in the cytoplasm of fibroblast cell lines.
Tissue Sections: The antigen is expressed in connective tissues which form a supporting network between parenchymal cells of all organs tested so far (see table below). Thus, the supportive mesenchymal structures of larger vessels can be studied. In spleen, a very clear delineation of red and white pulp is obtained. Capsule, sinuses, follicules, paracortex and medullary cords are also clearly delineated in lymph nodes.
Formulation Stock solution contains PBS, pH 7.2 with 5 mg/ml BSA as a stabilizer and 0.09% Sodium Azide as preservative
State: Purified
State: Lyophilized purified IgG fraction
Reconstitution Method Restore with 0.5 ml distilled water.
Concentration 0.4 mg/ml (after reconstitution)
Purification Affinity Chromatography
Conjugation Unconjugated
Storage Store lyophilized at 2-8°C for 6 months or at -20°C long term.
After reconstitution store the antibody undiluted at 2-8°C for one month 
or (in aliquots) at -20°C long term.
Avoid repeated freezing and thawing.
Stability Shelf life: one year from despatch.
Background Connective tissue consists of a ground of glycosaminoglycans, proteoglycans and glycoproteins through which various fibres run. These fibres can be collagenous, elastic or reticular. Reticular fibres are composed from the family of collagen proteins and give tensile strength. These fibres are made by reticular fibroblasts. 
Fibroblasts are the least specialized cells in the connective-tissue family. They are dispersed in connective tissue throughout the body, where they secrete a nonrigid extracellular matrix (ECM) that is rich in type I and/or type III collagen. Conective tissue consists of glycosaminoglycans, proteoglycans and glycoproteins through which various fibres run. These fibres can be collagenous, elastic or reticular. Reticular fibres are composed from the family of collagen proteins and give tensile strength. These fibres are made by reticular fibroblasts. The activation of fibroblasts by inflammatory stimuli results in their migration, proliferation and deposition of extracellular matrix components, important features involved in both wound healing and fibrosis.
